我有index.html和page.html
index.html有一个到page.html的锚点
我会按下按钮并向用户询问他是否真的要回到index.html
这是我的代码:
的index.html
<!DOCTYPE HTML>
<html>
<head>
<title>First App</title>
<script src="cordova-2.6.0.js"></script>
<script>
function onLoad(){
document.addEventListener("deviceready",onDeviceReady, true);
}
function onDeviceReady(){
navigator.notification.alert("PhoneGap is working!!");
}
</script>
</head>
<body onload="onLoad();">
<h1>Welcome to PhoneGap</h1>
<h2>Edit assets/www/index.html</h2>
<a href="page.html">Go to page</a>
</body>
</html>
page.html中
<!DOCTYPE HTML>
<html>
<head>
<title>First App</title>
<script src="cordova-2.6.0.js"></script>
<script>
function onLoad(){
document.addEventListener("deviceready",onDeviceReady, true);
document.addEventListener("backbutton", onBackKeyDown, false);
}
function onDeviceReady(){
navigator.notification.alert("PhoneGap is working!!");
}
function onBackKeyDown(e) {
navigator.notification.alert("PhoneGap back is working!!");
}
</script>
</head>
<body onload="onLoad();">
<h1>Welcome to PhoneGap Page</h1>
<h2>Edit assets/www/page.html</h2>
</body>
</html>
问题是没有处理后退按钮,但正确加载了cordova,因为我显示了警告框。
我做错了什么?
我有Android谷歌Nexus和Android 4.2.2
非常感谢。

将你的后退按钮监听器放在onDeviceReady函数中。
